- CryptoKeys plugin can now be told how many bits to use for keys. Defaults to 2048 as a happy medium between security and performance
- After creating the OpenSSL RSA key, use the exp/mod values directly rather than recomputing from primes
- Added RSA.h with some TBigInt based helpers for RSA keys
- Added FPakSignatureFile to wrap the contents of the pak .sig file, including determining that it is of a new format that supports versioning. Wraps the encryption and decryption of he master table hash
- Changed pak master signature hash from crc to SHA1
- Modified access to executable embedded public key data so that it is just an array of bytes. Will allow custom key sizes in the future.

- Added a "-sign" parameter to enable signing for the given pak. The cached settings in the crypto.json file aren't used to enable signing any more.
- Encapsulated all signing and encryption keys in a single keychain object which is passed around, rather than individual keys
- Added some validation to UBT/UAT encryption config parsing so that if you enable any signing or encryption stuff but haven't generated a key, it'll warn and disable everything.

The IMPLEMENT_MODULE macro now defines an empty function called IMPLEMENT_MODULE_{ModuleName}, to which we force a reference to via the linker command line. This behavior can be disabled on a per-module basis by setting bRequiresImplementModule = false from a .build.cs file.
